To all whom it may concern:

Be it known that .1, JOHN W. BAss -IAM,

a citizen of the United States, residing at Columbia, in the county it-M ry an tate" invented a new and use-,

of Tennessee, h I I ful Spring-Tire, of whi h the igngwing 1S a p cification.

The-device forming the Subject matter of this application is a spring tire,andnc 0b to provide-a tire ject of the invention is. wherein pneumatic elements subject to puncture and deterioration may be dispensed With. V V j I Another object of the invention is to improvethe spring construction whereby the resiliency in the tire is afforded. I

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the'above and tion andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes inthe precise embodiment of .the invention shown can be made without departing from the spirit ofthe invention. i

In the accompanying drawings V Figure 1 shows in side elevation, a device constructed in accordance with the invention, parts being broken away; Fig. 2 is a transverse section of the structure shown in Fig. 1; Fig. 3 is a horizontal section taken through the tire median plane thereof; sectional view showing the means the ends of certain ofnthe springs are secured; and Figs. 5 and 6 are perspective views disclosing portions of the base member. V

In the accompanying drawing, the numeral'l designates a wheel'body including a felly 2. Side plates 3 cooperate with the felly 2 and include clencherfianges 4. The side plates 31have wings 5 engaging the outer curve of the felly 2, the side plates being held to the felly by securing elements 6. A casing 7 is provided, the same having of the wheel-and rests upon the wings 5 of Specification of Letters lt atent.

7 other objects View, which will appear as the description pro-' at right angles to the Fig. a is a fragmental a whereby the side plates the base member preferably e ng made lot m talo the t ip out o wh ch th rings .10, are

ash on d ar ov r app as shown at 11',

- an a e onne tcd by se uri g elements 12.

A securing device 18 passes through the base member 9 and the o s {Patented Jun 22; 19.20: Ahplication iedrehruary & 0- Seria No. 4563- V overlapped ends 11 of the rings 10, the securing device 18 engaging the inner end 17 of the body 16 of th cruciform frame .15.

The cruciform frame 15'comprises lateral arms 19 projectingfrom the body 16. Tui bular'followers 20 aremounted to recipro cate in the arms 19,:the followers 20 having outer ends 21, attached by securing elements 22 to the ring 10. A follower 23 is mounted to reciprocate in the outer end of the tubular bodyilfion the frame 15 and has an outl rend 24 attached bywa securing element,

25 to the tread portion of the ring. If de-V sired, fillers 126 n1aybe interposed between the outer ends of the followers 20 andi-23c 7' I and the ring 10, a filler lo ein interposed between the inner end of the ody 16 of the frame 15 and the overlapped ends 11 of the ring'lO.

A compression spring 27 is located in the tubular body 16, one end of the compression spring abutting against the end 17 of the body, and the otherend of the compression spring abuting against the end21 of the follower 23. Springs'28 are located in the lateral arms 19 of the frame 15 and in the followers 20. The inner ends of the springs 28 are connected by caps 29 and fastening devices 30 to the body portion 16 of the frame 15. The outer ends of the spring 28 may be connected with the followers 20 in any desired way. If preferred the followers 20 may have-ears 31, through which the outer convolutions of the spring 28 are threaded. g

In order to facilitate the assembly of the base member 9 with the felly 2, it may be expedient to fashion the base member" in of the sections of the base member will ab'ut,

like a rule-joint, thus affording a relatively rigid and secure construction, when the base memberis in place on the felly 2 or,

more exactly speaking, on the parts 5, of

the'side'plates'3 In practical operation," considerable resiliency is afforded by the resilient rings '10.- When the rings 10 are compressed, the

springs 27 are compressed, the followers 23 moving inwardly; When the rings 10 are compressed, as aforesaid, the side portions of the rings tend to move outwardly,'carrying with them the" followers 20, the

springs 28 being put under tension. The generaljconstruction of the device, as above described is such that a highdegree of resiliency will be afforded, the device providing for a resiliency approaching'that of a pneumatic tire, without the disadvantages commonly and properlyattributed to a pneumatic tire.
